Update looking like new device set up - will it wipe trezor?

Hi there, apologies if this a a stupid question, I am not very technical.

I just tried to update my trezor one and it is now looking like a new device setup rather than a firmware update.

Is this normal? Should I proceed with the setup? I am worried that I will wipe my device if I do.

Thanks for the help

do you have your seed phrase ?
